"The cliffhanging denouement suggests that there is sure to be another book in the DI Kelly series, and I for one will be reading it."
Chloe Dunbar's claims that someone keeps breaking into her house while she sleeps, and that the police don't take her claims seriously. Then someone not only breaks in, but attacks her. In a news story compiled by an unscrupulous reporter, she blames her ex, Ricky. And in the subsequent report, the reporter implies that the team led by DI Ellen Kelly isn't doing its job properly. But Ricky has a cast iron alibi for the night of the attack, and the police have no leads. Kelly has her own problems to deal with. Her husband, Vinnie, was murdered five years ago, and Kelly took the law into her own hands in retaliation (see the first book in the series, 'Hunting Shadows'). Now she's back on the job, but still working under a cloud. Not only that, she realises that she has feelings for a man called Jim O'Dwyer, and is confused, especially as her two children seem to want the two of them to get together.
A woman called Monica complicates matters further, when she too claims that someone has been breaking into her house while she sleeps. Kelly surmises that these are copycat claims, based on the newspaper report, but when Monica mentions some things about the break-ins that were not in the report, Kelly has to take notice. Then people start getting murdered, and things get complicated. Do O'Dwyer and Monica know each other? Did Monica know Chloe? And who is Annie?
